SAW-SWAGING MACHINE.

SPECIFICATION forming part of Letters Patent No. 355,912, dated January1], 1887.

Application filed June 4, 1886.

T0 at whom it may concern:

Be it known that I, WILLIAM G. BAUM GARDNER, of Filer City, in thecounty of Manistee and State of Michigan, have invented a new andImproved Saw-Swaging Machine, of which the following is a full, clear,and exact description.

The object of my invention is to provide a new and improved saw swagingmachine which is automatic in operation and adjustable to saws of anysize or shape.

The invention consists of a sliding swagegate carrying a stationaryanvil-die, of an oscillating die operated from the main shaft, ofanautomatic clamp-lever, of an adjustable saw-blade holder, and of adevice for moving the saw.

The invention also consists of various parts and details andcombinations of the same, as will be fully described hereinafter, andthen pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front elevation of my improvement. Fig. 2 is an end viewof the same. Fig. 3 is a rear elevation of the same, parts beingremoved. Fig. 4 is a detail View of the dies and the swage-gate. Fig. 5shows detail views of the oscillating die and its carrier; and Fig. 6 isa sectional view of the main shaftand the friction-roller operating theswage-gate.

On the main frame A, of suitable construction, is mounted the, maindriving-shaft B, rotated either by means of a pulley, O, or a crank-arm,O. The front end of the shaft B is provided with a crank-arm, B, onwhich is mounted the friction-roller D, operating in the cam-groove E,formed in the swagegate .F, sliding in suitable bearings on the frame A.To'the swage-gate F is secured in an inclined position the stationaryanvildie G, of suitable The oscillating die H is held in a head, I,attached to a shaft, I, mounted in a bearing, F, on the swagegate F. Theshaft 1-is' provided with a sector-gear, J, which meshesinto asector-gear, J, secured to the main shaft B, and with a tripping -lug,K, which engages with the arm K, secured to the frame A, and having anupwardly-projecting inclined part, Kfl'on which rests the set-screw .L,screwed in the upper end of the clampinglever L, pivoted on the front ofthe swagegate F.

The main shaftB is provided with aneccentric, M, having the eccentric-strap M, the lower end of which is pivotally connected with the arm N,secured on the rocking shaft N,

mounted in abearing on the main frame A and carrying an arm, 0, on theupper end of which is pivoted thefeed-arm P,.oneend of which engageswith the teeth of the saw V to be swaged, and rests on an arm, Q,rigidly secured to the side ofthe frame A. In suitable bearingson'thefront of the frame A-slides the saw-gage plate R, provided withthe adjust= v able cross-head S, which is raised andlowered by the screwT, having a crank-arm, T, and mounted on the frame A. The saw-rest U isalso adjustable on the gageplate R. The main frame A is providedwith aset-screw, U, on which rests the swage-gate F when in its lowestposition.

The operation is as follows: The saw V to be swaged is placed in thesaw-gage plate'R,

and rests with its lower edge on the saw-rest V ,U, the dies H andGare'set to the shape of the teeth of the saw to be swaged, andthefeed-arm P is adjusted on the, arm 0 so as to move the saw vV one toothfor every revolution of the main shaft B. The stationary anvildie Grests against the front end of the tooth of the saw V, and the lower endof the clamplever L rests on the outside of the tooth of the saw andprevents the tooth from. bending sidewise under the pressure of theoscillating die H when the tooth is swaged. It will be seen that whenthe main shaft B is rotated the'friction-roller D will raise theswage-gate F, and at the same time the sawV will be moved the distanceof one tooth in the direction of the of the tooth by the action of thescrew L on the inclined arm K When the swage-gate F is in its lowestposition, the sector J on the rewolvingmain shaft 13 engages the sectorJ on the shaftl, and thereby turns the latter, so that the die If passesover the upper end of the respective tooth of the saw V and swages thesame. The swage-gate F is firmly held at rest during this operation andduring one-fourth of the revolution of the main shaft B by the peculiarform of the cam-groove E in the swagegate F. The action of thefriction-roller D in the cam-groove E then raises the swage-gate F, andthe tripping-arm K comes in contact with the lower end of the stationaryarm K, whereby the shaft I is turned to its former position and thesector J is again moved to such a position that the sector J will engagethe sector J in the next revolution of the shaft B.

The saw V is moved the distance of one tooth by the action of thefeed-arm P, as above described, so that the next tooth of the saw isswaged when the swage-gate F returns to its lowest position, as beforedescribed. The throw of the arm P can be regulated by the adjustment ofits pivot in the apertures O of the arm 0, or by adjusting the pivot ofthe eccentric-strap M in the apertures N of the arm N.

It will be seen that a saw of any size or shape cl ailn be automaticallyswaged by my device.

e tooth imparts a very fine steel-drawn temper to the cutting-edge ofthe tooth.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-'- 1. In a saw-swaging machine, thecombinatlon of a sliding swage gate carrying a stationary anvil-die, anda clamp-lever with an oscillating swaging-die, substantially as shownand described.
